I beleive the libdvdcss in the current CVS does that.
My query is, can it also be used to play encrypted DVD's from any region 
on a zoned DVD player? I have the libraries installed, but I'm not yet 
willing to fork out some money for a zone 1 disk if it won't work on my 
player (i'm zone 4).

Otherwise, can the regionset utility be used to 'unzone' a player?
